Kusintha kwa Nyengo, Mwayi Womwe Umabwera ndi Kuwala kwa Zomera za LED ku Kubzala M'nyumba

Zotsatira za kusintha kwa nyengo pakukula kwa mbewu. Kusintha kwa nyengo kwachititsa kuti pakhale kutentha kwa pamwamba, zomwe zachititsa kuti nthaka ikhale ndi tizilombo tating'onoting'ono, zomwe zimachititsa kuti nthaka iwonongeke kwambiri, zomwe zimachititsa kuti nthaka isawonongeke, kukokoloka, ndi mchere. Panthawi imodzimodziyo, kusintha kwa kutentha kwa m'madera kumakhudza kayendetsedwe ka madzi padziko lonse lapansi, kusintha kachitidwe ka mvula m'madera ndi kugawa kwa mvula, ndikuwonjezera zochitika zoopsa monga kusefukira kwa madzi ndi chilala. M'zaka zaposachedwapa, zochitika zamvula kwambiri zomwe zimachitika chifukwa cha kusintha kwa nyengo zakula kwambiri. Nthawi zambiri, kusefukira kwa madzi akum'mwera ndi chilala chakumpoto, ndipo dera latsoka likuwonjezeka, zomwe zimabweretsa kutsekeka kwakukulu kwa mbewu m'derali, komanso ngakhale kukolola. Kuonjezera apo, masoka a nyengo monga kutentha kochepa ndi kuwonongeka kozizira komanso kuwonongeka kwa kutentha komwe kumachitika chifukwa cha kusintha kwakukulu kwa nyengo yapadziko lonse lapansi. Nthawi zambiri, chizolowezi cha kuwonongeka kwa chisanu ndi kuwonongeka kwa chisanu kumpoto chakum'mawa ndi kumpoto kwa China chikuchulukirachulukira. Mchitidwewu, ngakhale zomwe zidakhudzidwa ndi ngoziyi m'madera ena, zidapangitsa kuchepa kwa 10% mpaka 18% pakupanga mpunga, zomwe zidakhudza kwambiri chitetezo cha chakudya m'dera lalikulu lopangira chakudya mdziko langa. Zotsatira za kusintha kwa nyengo pa njira yobzala mbewu. Kusintha kwanyengo padziko lonse kwathandizira kubadwa kwa mbewu zoyambirira m'madera ena okhudzidwa, kufupikitsa nthawi yobereka, komanso kufooketsa mphamvu yolimbana ndi kusintha kwa nyengo. Makamaka East China dera la dziko langa balere, tirigu ndi rapeseed mbewu. Mbewu zambiri zomwe zimabzalidwa m'derali ndi zamitundu yoyambirira. Chifukwa cha kutentha kwa nyengo yozizira, mbewu zimafupikitsidwa nthawi yachisanu. Chifukwa cha kutentha kwa nyengo, idayambika pasadakhale, zomwe zidafooketsa mphamvu yolimbana ndi kuzizira kwa mbewuyo, zomwe zidapangitsa kuti mbewuyo iwonongeke kwambiri ndi kuzizira kozizira, zomwe zidawononga kwambiri zokolola. Izi zinabweretsa mavuto atsopano pakusintha kachitidwe ka mbewu m'dziko langa. Chifukwa chakuti feteleza wa nayitrogeni angawonjezere kwambiri kupanga chakudya, feteleza wa nayitrogeni wapadziko lonse wakula mofulumira, ndipo nayitrojeni wa m’nthaka nawonso wawonjezereka. Phil ndi Robertson wa ku yunivesite ya Mi Ogin State amakhulupirira kuti mpweya wowonjezera kutentha umene umabwera chifukwa cha ulimi uyenera kukhala 8 % -14 % ya chiwerengero cha padziko lonse. Kafukufuku wasonyeza kuti alimi amatha kuchepetsa kugwiritsa ntchito feteleza wamankhwala pogwiritsa ntchito feteleza wolondola, potero amachepetsa utsi. CO2 high ndende inhibitory inhibitory Inhibitory Crop nitrite mu njira yosinthira kukhala mapuloteni. Kuphatikizika kwa nayitrojeni, komwe kumadziwikanso kuti njira yophatikizira nayitrogeni, kumachita gawo lalikulu pakukula kwa mbewu ndi kupanga. Mu mbewu zambewu, nayitrogeni ndiyofunikira kwambiri, chifukwa kugwiritsa ntchito nayitrogeni kupanga mapuloteni ofunikira pazakudya za anthu chifukwa mbewu zimagwiritsa ntchito nayitrogeni. Malingana ndi British "Guardian", asayansi adayesa kumunda pa tirigu, mpunga, chimanga ndi soya. Mayesowa adatsimikizira kuti mulingo wa CO2 wa CO2 udachepetsa kwambiri zakudya zoyambira za mbewu izi monga chitsulo ndi zinki. Panthawi imodzimodziyo, mapuloteni omwe ali m'mbewuzi amachepetsedwa. Malinga ndi kafukufuku, kulima tirigu wochuluka wa CO2 kumachepa ndi 9 % poyerekeza ndi nthaka yopingasa yokhazikika, kuchepetsedwa kwachitsulo ndi 5%, ndi mapuloteni amachepetsa ndi 6%; Momwemonso, zinc zomwe zili mu mpunga zomwe zimakula kwambiri CO2 zatsika. 3%, chitsulo chatsika ndi 5%, mapuloteni adatsika ndi 8%; Zinc ndi chitsulo zomwe zili mu chimanga ndi soya zinachepa mofanana, koma mapuloteni sanasinthe kwambiri. Mwachidziwitso, magazini ya "Natural Climate Change" inasindikiza "Tomlet of Nitrates of Growth Growth in the Fields" ikuponderezedwa ndi CO2 yokwezeka ". Kafukufuku wa pepalali akutsimikizira kwa nthawi yoyamba kuti kuchuluka kwa CO2 komwe kumakhala mlengalenga kwatsekereza njira yosinthira nitrate nitrate kukhala mapuloteni. Izi zikutanthauzanso kuti kusintha kwa nyengo kukuchulukirachulukira, zomwe zipangitsa kuti mbewu zachakudya zisadye bwino. The organic nayitrogeni munali mankhwala m'nthaka makamaka anachokera kuwonongeka kwa nyama, zomera ndi tizilombo ting'onoting'ono matupi, koma ambiri nayitrogeni munali mankhwala ndi insoluble m'madzi ndipo kawirikawiri ntchito zomera. Zomera zimatha kuyamwa ma amino acid pakati pawo. , Non-sungunuka organic nitride monga amide ndi urea. Choncho, organic nayitrogeni alcohols makamaka zochokera ammonium ndi nitrate, mlandu 1 % -2 % ya nthaka nayitrogeni zili. Chomeracho chikatenga mchere wa ammonium m'nthaka, chimatha kuugwiritsa ntchito mwachindunji kupanga ma nitrides achilengedwe monga ma amino acid; Ngati nitrate imatengedwa, iyenera kubwezeretsedwanso kuti igwiritsidwe ntchito. Mwachidule, mmerawo umamwetsa ammonium kuchokera m'nthaka, kapena nthawi yomweyo amakokedwa ndi amino acid ammonium itachepetsedwa ndi kuchepa kwa nitrate. Kusakaniza kwa ammonia kumachitika muzu, chotupa cha muzu ndi tsamba. M'zaka makumi angapo zikubwerazi, mapuloteni onse amatha kuchepa ndi pafupifupi 3%. Pakali pano, atatu-dimensional kubzala luso la yogwira chitukuko cha mayiko European ndi America ndi ena Southeast Asia sadya nthaka chuma. Malo otsekedwa ogwiritsira ntchito nthaka amachepetsa kuwonongeka kwa nthaka. Yaikulu -mwayi ntchito zomera zowonjezera kuwala amathetsa kupanda kuwala m`nyumba atatu azithunzithunzi kubzala. Pa nthawi yomweyo, sipekitiramu wa zomera zowonjezera kuwala akhoza makonda malinga ndi zomera zosiyanasiyana. Njira zamakono zopangira mawonekedwe opangidwa bwino. Zhuhai amagwira ntchito yopanga mitundu yosiyanasiyana ya mikanda ya nyali ya LED. Posachedwapa, kufunikira kwa mikanda ya nyali ya LED kwakulanso. Ngati mukufuna kuyitanitsa mikanda ya nyali ya LED, mutha kufunsa makasitomala kuti akonze.
